ACTDEP037: Select and justify choices of materials, components, tools, equipment and techniques to effectively and safely make designed solutions.

Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as sustainable resource management practices in mining regions like the Kimberley and Pilbara, to demonstrate respect for community values and environmental stewardship.

Cross-Curriculum Priority: Sustainability - Students explore sustainable practices in metal sourcing and recycling, including Indigenous land management techniques that promote environmental balance.

Reading: Sustainability in Metal Sourcing and Recycling

Sustainability in metal sourcing and recycling is essential for reducing environmental impact and conserving resources. Mining metals like iron, copper, and aluminium can cause habitat destruction, water pollution, and carbon emissions. Sustainable sourcing involves ethical mining practices, such as rehabilitation of land and using renewable energy. Recycling metals saves energy, as remelting scrap requires less power than extracting from ore. For example, recycling aluminium uses 95% less energy. Processes include collection, sorting, shredding, and melting to create new products. Benefits include reduced landfill waste and lower greenhouse gas emissions. In design and technologies, students choose recycled materials for projects to promote circular economy.

Aboriginal communities in Kimberley and Pilbara practice traditional land management, emphasizing respect for country and minimal disturbance, aligning with modern sustainability. Year 7 students learn to integrate these principles for responsible design. Understanding sourcing and recycling ensures future resource availability. (Word count: 350)
